954 sprockets upgrade

I have been using the same sprocket sizes on my bike since I purchased it which is16/43 my question is can I put a 17/42 on my 954 without making any damage to it? is that a good combination?

That combo will be fine but it will take away some of your acceleration while offering a slight top end speed increase. (Though I don't know if the bike really has the power to get any more out of that gearing).

Usually street bikes go down in the front and up in the back for better low end pick up.

You'll also need to keep in mind that changing gearing will throw your speedometer off (unless it runs off a front wheel sensor instead, which I believe my Kawasaki does but not my Suzuki).

Check gearingcommander.com you can play with different set ups and check the theoretical differences between them, I have a 929 and tbh, just dropping one on the front was good enough for me, I don't see the need of top speed on the mean streets, so quick acceleration was def a better choice.

Go 16/45...lower gearing is better acceleration and response... MORE FUN..

Unless you need to go over 165-170 mph... if that's the case, go taller on the gearing.

No offense meant. Reducing the diameter of the front sprocket in relationship to the rear sprocket creates a higher ratio, so does increasing the rear sprocket diameter. From the average I've heard/seen/insomecasesmeasured, reducing 1 tooth in front is equal to 3 up in the back. Understanding that, if you went up one in the front, it would the same as reducing ~three in the back (all of this resulting in a -1 in sprocket change).

Is this what you want? Less 0~60 and more 80~ cruising speeds?

Either way, no harm to the engine/gearbox with what you are doing.
